Typically, the effectiveness of agricultural and forestry BMPs is evaluated based on in-stream measurements of nutrients and sediment. However, as can be seen from the wide range of reduction efficiencies attributed to any BMP from published research, a large number of climatic, fate, and transport variables often obscure cause and effect relationships and the exact mechanisms responsible for load reduction. In-stream pollutant reductions from BMP implementation are also typically not immediate, but gradually accrue over time as vegetative BMPs mature, or while BMPs reduce nutrient build-up in the soil or bacteria attached to channel sediments. Because of these uncontrolled variables and time lags between BMP implementation and pollutant reduction, BMP performance efficiencies are difficult to evaluate.
